| Abstract: |
| 【Objective】 According to northwest natural conditions, climate and resources,an eco-campus mode was built with biogas as link in Fanjiazhai Middle School,then its economic benefit was analyzed.【Method】 Take Fanjiazhai middle school as an example of eco-campus to introduce mode's construction,and the straw-sheep(toilet)-biogas-fruit mode was analyzed through financial analysis.【Result】 Results show that the net Present Value >0,the Economic Internal Rate of return is 0.13>Basic Discounted Rate,the benefit (total income/total cost) is 1.077>1.【Conclusion】 The mode has good economic benefit,and deserves popularization in northern area. |
